MILK-BOTTLE STOPPER AND POURING- SPOU T.

ApplicationfiledAugust 5, 1922. Serial No. 579,896.

To all whom it may concern:

Be itknown that we, JoHN- T. MARSHALL and SAMUEL LnAvrr'r, citizens of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in lflilk-Bottle Stoppers and Pouring Spouts, of which the following is a specification, reference being'had to the accompanying drawings.

This invention relates to closures for bottles, jars and the like, and particularly to a closure for milk bottles.

The general object of the invention is to provide a stopper or closure which is adapted for use with practically all standard milk bottles, although adapted for use with other kinds of jars or bottles, which has associated therewith a spout andwwhich is so constructed that when the spout is turned into one position the pouring opening is closed and no milkmay be poured from the bottle, nor can any dust or other foreign matter enter the bottle.

A further object is to provide a device of this character which is very simply con structed, very cheaply made, and which may be readily taken apart so that all of the separate piecesfrom which the stopper is 30, made may be cleansed and. rendered sanitary.

A still further object is to provide a device of this character which is very simple and, therefore, which is relatively cheap.

Our invention is illustrated in the accompanying c drawings, wherein Figure 1 is a vertical sectional view through a jar showing the closure in elevation; s

Figure 2 is a fvertical sectional view through the closure, the spout in its open position; I

Figure 8 is a like view showing the spout closed;

struction as shown in Figure 1;

Figure '5 is a top'plan View of the struci ture shown in Figure 1.

Referring to these figures, 1t Wlll be seen i that our device comprises a plug or cork to Figure 2, but

Figure 4 is a front elevation of the con-- designated 10, which is of such diameter as to fit firmly in place in the mouth of a milk bottle. Extending through a central opening 11 in this cork or plug 10 and forming a lining therefor is a metallic sleeve v12 whose inner end is slightly flanged, as at 13,

to prevent it from pulling through the cork l0 and whose outer end is flanged and over-, lies the face of the cork or stopper and then is rebent upon itself, as at 14, and thenv upwardly extended, as at 15, this upwardly extending portion being impressed with screwthreads. The upwardly extending,

screw-threaded flange 15is disposed outward of the sleeve 11 so that a ledge is left, upon which lodge is disposed a cork gasket or seat 16, this being forced into place and held by the interior screw-threads of the flange 15. This gasket or seat is, of course, annular in form and the upper face is beveled, as atl7. c

Detachably engaging the screw-threaded flange or neck 15 is a cap, designated generally 18, which is pressed out of metal or otherwise formed. This cap is circular incross section andhas its wall screw-threaded to engage with the exterior screw-threads of the flange or neck 15, and above these screwthreads the cap extends upwardly and centrally, as at 19. The center of this domical portion 19 is out out, as at 20, and the side wall of this domical portion is cut out, as at 21. Thus a continuous slot is formed whose upper portion is concentric to the axis of the domical cap 19, and this slot 'eX- tends downward to the screwthreaded portionlS. Coacting with this cap 18 is a spout 22 whose base 23 is bulbous origlobular, this spout having such a diameter that it fits snugly within the aperture c 20 when the spout is turned into alignment with the axis of the cap 18, as illustrated in Figure 2. The bulbous portion fits within the domical portion 19 and when the spout is in its pouring position, as shown in Figure 3, the aperture 2d at the lower end of the bulbouspor-c tion registers with the aperture in the cork seat or gasket 16. The slot 21, however, permits this pouring spout to be turned into 11 so that the side wall of the globular portion 23 will close the opening through the gasket 16..

It will be obvious that in either of these positions it is impossible to remove the spout 22 from its engagement with the cap 18. It

' seat formed will be also obvious that the bulbous portion of the spout will fit down firmly upon the by the cork gasket 16 and will tightly close against the stem so that the passage of liquidthrough the stopper will be absolutel prevented. When the spout is turned to its position of alignment, as in Figure 2, of course the liquid may be readily discharged through this spout. It will be seen that the globular base of the pouring spout has very tight engagement with the concave face of the seat 16 and with the inner face of the domical portion of the cap 18. I

It will be seen that this construction provides a pouring spout which is sanitary, sim-. ple, and readily assembled or disassembled so that it may be readily cleaned and kept fit for use. spout is turned into right angles to the axis of the opening through the gasket that air,

dust or other foreign matter will be vprevented from coming in contact with the milk or other liquid in the bottle. 7

It is to be noted that the bulbous portion 23 of the spout does not form a perfect sphere or globe but that there are three circumferentially extending facets defined by the lines a and b and that the cap 18 is formed at the base of the domical portion with a circumferentially extending depression 0. This construction frictionally locks the spout either. in its vertical position or in its angular position. When the spout is in its vertical position, the depression 0 striking against that face of the base of the spout between the lines a and b tendsto hold the spout in its vertical. position and, on the other hand,-when the spout turned to its angular position the portion between the lines a, and b fits within the aperture of the seat or gasket 10 and tends to prevent the spout from being turned outward. The domical portion of the spout, of course, has frictional engagement with the bulbous portion 23, which will also tend to prevent free movement of the spout, and this may be increased, of course, by turning the cap 18 down upon the screw-threaded flange of neck 15.

.While we have particularly designed this stopper for milk bottles, it is to be understood that it may be used in other situations and that modifications might be made in the details of construction and arrangement of parts without departing from the spirit of the invention as defined in the appended claims. It will be seen that no brazing or soldering is required in order to attach the Furthermore, when the pouring parts to each other and that all the parts may be stamped or spun from sheet metal.

We claim 1. A closure of the character described comprising a bottle stopper having a central aperture, a metallic sleeve disposed in said aperture. and flanged upon the inner end of the stopper and at its outer end outwardly flanged upon the face of the stopper,

then extended inward and then upward, the

upwardly extending portion forming a neck and being exteriorly and interiorly screw-threaded, said neck being disposed outward of the sleeve to form a ledge, a gasket of fibrous material forming a seat inserted in said neck and resting upon the ledge and having a concave upper face, a cap having detachable,screw-threaded engagement with the neck, the cap having a domical upper portion formed with a slot extending from the top of the cap down ward nearly to the base thereof, and a spout having a neck operating in said slot, and an integral, hollow, globular base fitting the interior of the cap and the concavity in the seait, the base having an opening at its lower enc.

2. A pouring closure for receptacles comprising a support adapted to be inserted in the neck of the receptacle and having an interiorly screw-threaded neck, a fibrous seat disposed within the neck and having a concave upper face, a domical cap having screwthreaded engagement with the neck and having a slot extending from the top of the cap down one side thereof, said cap being formed with a circumferentially extending indentation, and a spout having an integral, globular base portion fitting the domical portion of the cap and fitting said seat, the neck of the spout extending out through said slot, the base portion of the spout having circumferentially extending facets coacting with the seat and with the indentation of thecap to impede the free oscillation of the spout.

A pouring closln'e for receptacles comprising a stopper adapted to be inserted in the neck of the receptacle and having associated therewith a cap having a slot extending from the top of the cap down one side thereof,'the cap being formed with a' circumferentially extending indentation and there being a seat disposed within the cap, and a spout having a globular base portion fitting the domical portion of the cap and said seat, the neck of the spout extending out through said slot, the base portion of the spout having circumferentially extending facets coacting with the seat and with the indentation of the cap to impede the free oscillation of the spout. i

4:. A'pouringclosure for receptacles comprising a stopper adapted to be inserted in the neck of the receptacle and having'assoadapted to yieldingly hold the spout in alignment with the axis of the stopper or at right angles thereto. 10

In testimony whereof We hereunto effix our signatures.
